Is this any reason for my boyfriend to be upset?

[Mickey Yoochun]

I understand guys dont often like to show when they're upset or signs of weakness, especially if they're the mocho type, but he always acts out passively aggressivley. Yesterday was my first time re-activating my facebook in 2 years. When I reactivated it, I still had all these old pictures of my ex and I. I guess thats around the time I tried deleing my fb. Anyways, so he gets mad and then curious and starts looking me up online and finds all these social networking sites that I hadnt been on in ages. My last post on twitter was in 2011, and on my profile I had put something like "waiting for that great guy to come along" or something like that. He gets mad about that, and then finds my super old myspace that I hadnt been on since 2009. I have a whole bunch of bad pictures on there cause I use to be those "myspace whores" when I was a teenager. But, I dont remember password to myspace anymore, and I cant get it emailed to me cause i used a fake email address. But it doesnt matter to me. I dont know why it should to him if I havnt been on there in ages. And now hes not talking to me....isnt he overreacting? Or am I in the wrong? We've been together for a little less than a year, and hes just now findng all this stuff
@'lyssa He's 19 :/
